Question

Answer the questions below.

Answer 1

Answer:

(a) 85m

(b) 61cm

Step-by-step explanation:

(a) We know that the formula for the perimeter of a rectangle is $2(a+b)$, where a is the length and b is the width, or vice versa. So for this garden, $2(a+68)=306\\a+68=153\\a=85$(m)

(b) We know that the formula for the area of a rectangle is $L*W$, where L is the length and W is the width. Note that these values are interchangeable, e.g. 2*3=3*2=6. So for this window,

$84*W=5124\\W=61$(cm)
