Question

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

Answer 1

Answer:

b = $\frac{A-lw}{0.5h}$

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 = $\frac{A-lw}{0.5h}$

Answer 2

Answer:

Option 2 - $b=\frac{A-lw}{0.5h}$

Step-by-step explanation:

Given : 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 $A = lw + 0.5bh$

To find : Solve for b?

Solution :

Step 1 - Write the formula,

$A = lw + 0.5bh$

Step 2 - Subtract 'lw' both side,

$A-lw=0.5bh$

Step 3 - Divide by 0.5h both side,

$\frac{A-lw}{0.5h}=b$

Therefore, $b=\frac{A-lw}{0.5h}$

So, Option 2 is correct.
