x = 180-105-42
x=33

Hope this helps!! :)

Answer:

$150

Step-by-step explanation:

→ Find 3/5 of 1500

( 1500 ÷ 5 ) × 3 = 900

→ Find 6/20 of 1500

( 1500 ÷ 20 ) × 6 = 450

→ Find the sum of the 2 numbers

900 + 450 = 1350

→ Minus it from the original 1500

1500 - 1350 = $150

Setler79 [48]

the largest rectangular area is actually a square.

so the side would be 400/4 = 100 feet

area of a square is S^2

100^2 = 10,000 square feet
