Question

Answer asap!!! which equation could be used to find the perimeter of a rectangle that has a width of 10 inches and a length of 20 inches?

a. p= 2⋅10 + 2⋅10
b. p= 20⋅10
c. p= 10+20
d. p= 2⋅20 + 2⋅10

Answer 1

d. p = 2*20 + 2*10

Explanation:

You know to find the perimeter, just add side + side + side + side.

And two pairs of sides on a rectangle are congruent, so the missing side lengths based on the width and length, will be 20 & 10.

So add 20 + 20 + 10 + 10.

To simplify this, say 2*20 and 2*10. And then add them.

So it is D
