Question

A rectangle has an area of 524.4m2. One of the sides is 6.9m in length. Work out the perimeter of the rectangle. PLEASE ANSWER!!! SOON ASAP

Answer 1

165.8 m

Solution,

Area of rectangle= 524.4 m^2

Length(L)= 6.9 m

Breadth(B)=?

Now,

`area = length * breadth \\ or \: 524.4 = 6.9 * b \\ or \: 524.4 = 6.9b \\ or \: b = (524.4)/(6.9) \\ b = 76 \: m`

Again,

Perimeter of rectangle:

`2(l + b) \\ = 2(6.9 + 76) \\ = 2 * 82.9 \\ = 165.8 \: m`

Hope this helps...

Good luck on your assignment.....

Answer 2

The perimeter of the rectangle is 165.8cm

Explanation:

Area of a rectangle = length × width

Area = 524.4m²

length = 6.9m

524.4 = 6.9 × width

width = 524.4 / 6.9

width = 76m

Perimeter of a rectangle =

2(length ) + 2(width)

length = 6.9m

width = 76m

Perimeter = 2( 6.9) + 2(76)

= 13.8 + 152

The final answer is

= 165.8cm
