Marcie wants to enclose her yard with a fence. her yard is in the shape of a rectangle attached to a triangle. the formula for the area of the enclosed space is a = lw + 0.5bh. solve for b.
b = a/ iw + 0.5h
b = a - iw / 0.5h
b = a − lw − 0.5h
b = a + lw + 0.5h

b =

Step-by-step explanation:

Let

l------> the length side of the rectangle

w----> the width side of a rectangle

b----> the base of the triangle

h----> the height of the triangle

we know that

the area of the yard is equal to

A = lw+0.5bh

Solve for b------> ( that means clear variable b)

Subtract lw from both sides

A-lw = 0.5bh

Divide by 0.5h on both sides

b =

answer: 1) twenty-seven times y

              2) twenty-seven multiplied by y
