Question

Calculate the perimeter of rectangle whose area is 4900msquare and length is 140m​

Answer 1

350 meters.

Explanation:

Since we already know that the length is 140 meters, we can easily find the width by dividing the area (4900 square meters) by 140 meters:
`(4900)/(140)=35`. Now that we know the width is 35 meters, we can plug it in to find the perimeter. Know that the formula to find the perimeter of a rectangle is
`P=2(l+w)`. Plugging it in, we get
`P=2(140+35)=2(175)=350`. The perimeter of the rectangle is 350 meters.
