The area of a racquetball court is 800 square feet. the length of a standard court is twice as its width. what are the dimensions of a standard racquetball court?

Given - area of a racquet ball court is 800 square feet.

length is the twice of the width

find out thedimensions of the racquet ball court.

To proof -

Formula

area of a rectangle = length×breadth

 as given inthe question the length of court is twice of its width .

let assume width be w

than  length become 2w

put in the formula

w×2w = 800 ft²

2w² = 800 ft²

w = ft

w = 20 ft

Than the length become 40 ft.

Hence proved

38.5

step-by-step explanation:

lets say, first number = r

second number = 3r+7

total = 49

(r)+(3r+7)= 49

4r+7 = 49

4r = 42

r = 42/4

r= 10.5

3r+7 = 3(10.5)+7 = 38.5
