Question

A square has an area of 25 square cm. Draw a straight line to divide into two equal

rectangles. What is the area of each rectangle?​

Answer 1

Step-by-step explanation:

Given:

1. A square of area 25cm².
2. A straight line is drawn to divide the square into equal rectangles.

To find: Area of rectangle formed when a straight line is drawn to divide into two equal rectangle

Formula of area of square= (side)².

=> 25cm²=(side)²

=> √25cm²=side.

=> 5cm= side.

If a line is drawn to divide it, then two sides are divided into equal lenghts.

i.e., breadth of each equal rectangle=5/2=2.5cm.

Now, In each rectangle l=5cm and b=2.5cm.

Formula of area of rectangle=l×b

Area of each rectangle=5×2.5=12cm².

Answer 2

Answer:

Area of square is 25 then each side of square is 5

when it divide into two equal

area of rectangle = l × b

= 2.5 × 5

= 12.5
