The Area of Rectangular Lawn is 255m².
If it's Length is 15m, Find it's perimeter.

Please help :((​

Answer 1

Area of rectangular lawn is 255 and l=15

Formula to find area =length×bredth

So,15×b=255

B=255/15

B=17

Perimeter of rectangular lawn is =2(l+b)

Perimeter=2(15+17)

Perimeter=2×32

=64. Ans

Answer 2

Given:

The area of the rectangular lawn = 255m²

Length = 15m.

To Find:

The perimeter of the rectangular lawn.

Solution:

Let the width of the rectangular lawn be x.

According to the formula,

The area of the rectangle = length × width.

The area of the rectangle = 15 × x.

The area of the rectangle = 15xm².

We have given,

The area of the rectangular lawn = 255m².

so,

255 = 15x.

x = 255/15.

x = 17m.

The width of the rectangular lawn = 17m.

Now,

The perimeter of the rectangular lawn = 2 × (length + width).

The perimeter of the rectangular lawn = 2 × (15 + 17)m.

The perimeter of the rectangular lawn = 2 × 32.

The perimeter of the rectangular lawn = 64m.

Hence, the perimeter of the rectangular lawn is 64m.
