Question

find the perimeter of a rectangular playground whose area 360m and length is 90m​

Answer 1

188m

Step-by-step explanation:

Length = 90m

Area = Length × Breadth

360 = 90 × Breadth

Breadth = 360 ÷ 90

Breadth = 4m

Perimeter = 2 (Length + Breadth)

= 2 (90m + 4m)

= 2 × 94m

= 188m

Answer 2

Answer:

188m

Step-by-step explanation:

Given,

length of a rectangular playground=90m

Area of a rectangular playground= 360m

we know that,

Area of a rectangle = l×b

360m = 90×b

360 = b

90

4m = b

Now,

Perimeter of rectangle= 2(l+b)

= 2(90+4)

= 2×94m

= 188m
