Question

rectangle A has a length of 24 meters and a width of 20 meters. rectangle B has the same area as rectangle A. the width of rectangle B is 12 meters less than the width of rectangle A. what is the length of rectangle B ?

Answer 1

To solve this, first we'll find the area of the rectangle A,

Area=length × width
?=24m×20m
480m=24m×20m
480m squared=area of the rectangle A

now we'll find the width of rectangle B,
"the width of rectangle B is 12 meters less than the width of rectangle A",
20m-12m= 8m
8m=width of rectangle B

finally we'll find the length of rectangle B,
area of the rectangle B= 480msquared
width= 8m
length=? (to find this divide the area by the width)
480÷8=60m
length of the rectangle B=60m
