Question

A rectangle has an area of 513.5m2. One of the sides is 7.9m in length. Work out the perimeter of the rectangle

Answer 1

Step-by-step explanation:

perimeter of rectangle is2*l+b=2*513m2+7.9

Answer 2

The perimeter of the rectangle is 145.8 m .

Explanation:

WE know that the area of a rectangle is given by :-

Area = Length x Breadth

Given : The area of rectangle = 513.5 m²

One side has length =  7.9m

Then , length of other side = ( area of rectangle ) ÷ (length of side)

=  513.5 ÷ 7.9 =65 m

Perimeter of rectangle = 2 (sum of adjacent two sides)

= 2(7.9+65)

=145.8 m

Hence, the perimeter of the rectangle is 145.8 m .
