Question

a rectangular field has perimeter 186m and breadth 35m. Find it's length.

clear explanation needed.​

Answer 1

Answer:

length = 58 m

Step-by-step explanation:

given -

Perimeter of rectangle = 186 m

Breadth of rectangle (b) = 38 m

to find -

Length of rectangle (l)

solution -

as we know that perimeter of a rectangle = 2(l+b)

so

perimeter of rectangle = 186 m

2×(l+b) = 186 m

l+b = 186 m ÷ 2

l+b = 93 m

l + 35 m = 93 m

l = 93 m - 35 m

l = 58 m

Hence the length of rectangular field = 58 m.

hope it helps.

Answer 2

$perimeter \: of \: rectangular \: fied \: = 2(l + b)$

$186 = 2(l + 35)$

$186 = 2l + 70$

$186 - 70 = 2l$

$116 = 2l$

$\frac{116}{2} = l$

$58 = l$

$Therefore,</p><p>length \: of \: the \: rectangular \: field \: is \: 58m$
