Question

draw a rectangle with side 5cm and 3cm. draw a square of the same area.

Answer 1

Step-by-step explanation:

Required to construct: A triangle, the area of which = a square with side 5cm

Given: A square ABCD , each side = 5cm

Step 1 : Extend any one side AB of the square, to P, such that AP = 10cm.

Step2: Take an arbitrary point Q on the line coincident to opposite side DC. ( ie extended line DC)

Step3: Join A& Q . Then Join P&Q.

Triangle APQ so formed is the required triangle.

Justification: area( square ABCD) = AB * BC = 25 cm²

area( tri APQ ) = 1/2 * base * corresponding altitude

= 1/2 * AP * BC

hope that this will be helpful for you

please follow and mark as brain list

please

= 1/2 * 10 * 5

= 25 cm²
