<h3>What is a rectangle?</h3>
A rectangle is a four-sided figure in which opposite sides are equal and the diagonals are also of the same length.
Given Ed's living room is 4 yards wide and 7 yards long.
We know that the area of a triangle is the product of its length and width.
∴ The area of Ed's living room is (4×7) sq yards = 28 sq yards.
Also given to install yellow carpet that costs $5.00 per square yard,
∴ For 28 sq yards, the cost of installing a yellow carpet will be,
= (28×5) dollars.
= 140 dollars.

Answer:
Write an equation for each statement:
:
"one number is four more than a second number."
x = y + 4
:
" two times the first number is four more than four times the second number"
2x = 4y + 4
;
From the 1st equation, substitute (y+4) for x in the above equation
2(y + 4) = 4y + 4
2y + 8 = 4y + 4
8 - 4 = 4y - 2y
4 = 2y
y = 4%2F2
y = 2, the second number
and
x = 2 + 4
x = 6, a number
