Arectangle with a width of 8 inches has a perimeter measuring 40. which equation can be used to determine l, the length of the rectangle?

Perimeter = 2w + 2l

40 = 2*8 + 2l

2l = 24

length = 12 inches

Therefore, equation G is what you'll need.

Step-by-step explanation:

answer: the angel abc is 30°,and the abc is a triangle where the angel bac is 90°

so ac is the half of 24=12ft,and from the pythagorean theorem we find ba

ba=√bc^2-ac^2=√576-144=√432=12√3ft

so bac is 12+12√3=12(1+√3)ft
