Question

2.2

Determine the length of the rectangle if the area is 800 cm² and the breadth is 20 cm
​

Answer 1

40 cm

Explanation:

The area (A) of a rectangle is calculated as

A = lb ( l is the length and b the breadth )

Here b = 20 and A = 800 , then

l × 20 = 800 ( divide both sides by 20 )

l = 40 cm
