## How can we draw a square of area 15 square centimeters?

Steps of construction:

1. Draw a line BC = 5 cm, taking B and C as centres, draw.
2. Join AD to get rectangle ABCD, here area(ABCD) = length × breadth = 5 × 3 = 15 cm.
3. From the rectangle drawn, extend AD by 3 cm to D’.
4. Now, draw a chord PQ ⊥ AD’, passing through D.
5. Taking DP as side, draw a square DPRS, which is required.

### How do you draw a square shape?

Draw a Square or Rectangle

1. Click Rectangle on the Drawing Objects toolbar and position the pointer where you want to include the square or rectangle on the diagram window.
2. Click the area and drag from the upper left to the opposite end of the square or rectangle.
3. Release the mouse button.

#### How do you draw a simple square?

Place the spike of the compass on point Q and draw an arc somewhere below the arm MN. Place the spike of the compass on point P and draw another arc which cuts the arc drawn in the previous step at some point (say R). Connect the points P and R and the points Q and R using a straightedge. The figure PMQR is a square.

How do you draw a square of 4.5 cm?

Steps:

1. Draw a line segment AB = 4.5cm.
2. Draw AP ⊥ AB.
3. From AP cut off AD = 4.5cm.
4. With B as a center and radius 4.5 cm draw an arc.
5. With D as center and radius 4.5 cm draw another arc cutting the former arc at C.
6. Join BC and CD.

## How do you square the area of a square 6 cm?

Construct a square whose diagonal is 6cm. Measure the side. Find also its area.

1. Draw the rough diagram and mark the given measures.
2. Draw a line segment AC=6cm.
3. Draw a perpendicular bisector XY of AC.
4. XY intersects AC at O.
5. With O as centre, draw two arcs of radius 3cm cutting the line XY at points B and D.

### How do you find the area of a rectangle with 12 square centimeters?

Draw the base AB of 4 cm. Construct 90° angles at both points A & B. Take 3 cm radius and draw arcs from both points A and B. Join CD.

#### Which key is used to draw a square?

Hold down the “Alt” key, and then type “9632” to form a large, solid square. To form a small solid square, type “Alt” plus “9642.”

Why is it called T-square?

A T-square is a technical drawing instrument used by draftsmen primarily as a guide for drawing horizontal lines on a drafting table. It may also guide a set square to draw vertical or diagonal lines. Its name comes from its resemblance to the letter T. Higher-end table saws are often equipped with T-square fences.

What are the units in a square calculator?

The units are in place to give an indication of the order of the calculated results such as ft, ft 2 or ft 3. Any other base unit can be substituted. A square is a convex quadrilateral with all sides equal length and positioned at right angles to each other. Or, a square is a regular polygon with four sides, a tetragon.

## How to calculate the area of a square?

A square is a convex quadrilateral with all sides equal length and positioned at right angles to each other. Or, a square is a regular polygon with four sides, a tetragon. Area of a square: A = a 2

### How to calculate the square of a side?

Square Calculations. Calculate q, P, A | Given a. Given the length of a side calculate the diagonal, area and perimeter. q = a√2. A = a 2. P = 4a. Calculate a, P, A | Given q. Given the diagonal length calculate the side length, perimeter and area. a = q / √2.
