Formula- Area = L • W

So...

Length = 18 + 3

Width = 18 + 3

Since you’re adding 18 + 3 for Length AND Width, you’re going to get a sum of 21 for each.

Length = 21

Width = 21

Now you’re gonna want to multiply 21 by itself.

21 • 21 = 21 + 420 = ?

Which leaves you with the final sum of...

Area = 441 yds.

A trapezoid has an area of 42 square miles. One base is 4 miles long. The height measures 6 miles. What is the length of the oth

loris [4]

The length of other base of trapezoid is 10 miles

Step-by-step explanation:

The formula for area of trapezoid is:

$A=\frac{h}{2}(b_1+b_2)$

We know that

A = 42 square miles

b_1 = 4 miles

h = 6 miles

Putting the values

$42=\frac{6}{2}(4+b_2)\\42=3(4+b_2)\\42=12+3b_2\\Subtracting\ 12\ from\ both\ sides\\42-12=12+3b_2-12\\3b_2=30\\Dividing\ both\ sides\ by\ 3\\\frac{3b_2}{3}=\frac{30}{3}\\b_2=10\ miles$

The length of other base of trapezoid is 10 miles
