Question

The perimeter of a rectangular plot is 248m and it's breadth is 42m.Find it's (i) length (ii) area

Answer 1

Answers:

(i) Length = 82 m

(ii) Area = 3,444 m²

Explanation:

1- getting the length of the plot:

The perimeter of a rectangle is calculated as follows:

Perimeter = 2(length + breadth)

We are given that the perimeter is 248 m and that the breadth is 42 m

Substitute with the givens in the above equation to get the length as follows:

Perimeter = 2(length + breadth)

248 = 2(length + 42)

length + 42 = 248/2

length + 42 = 124

length = 124 - 42

length = 82 m

2- getting the area:

The area of a rectangle is calculated as follows:

Area = length * breadth

We have the length = 82 m and the breadth = 42 m

Therefore:

Area = length * breadth

Area = 82 * 42

Area = 3,444 m²

Hope this helps :)
