<span>Based on hint and given formula, we can complete the problem. The question asks for square feet of grass so we know that we are solving for the area, A. It also tells us the height (looking downward) of the field is 75 ft,h, while the two bases are 125 ft and 81 ft (b1 and b2). So we can solve the equation. A = 75((125+81)/2) A = 75(206/2) A = 75(103) A = 7725 The area of the field is 7725 square feet.</span>

Manny wants to proportionally enlarge a rectangular window that has a length of 36 inches and a width of 24.5 inches.

stira [4]

The new width of the window should be 36.75 inches ⇒ 2nd answer

Step-by-step explanation:

The proportionally is two quantities having a constant ratio

The quantities y and x are proportional if:

$\frac{y}{x}$ = k, where k is the constant of proportionality
y = k x
$\frac{y_{1}}{x_{1}}=\frac{y_{2}}{x_{2}}$

∵ Manny wants to proportionally enlarge a rectangular window

- That means the new dimensions are proportion with the

original dimensions

∴ New dimensions = k × original dimensions

- k is the constant of proportionally

∵ The original length = 36 inches

∵ The new length = 54 inches

- Substitute then in the equation above to find k

∵ 54 = k × 36

- divide both sides by 36

∴ 1.5 = k

∴ The new dimensions = 1.5 × original dimensions

∵ the original width = 24.5 inches

∴ The new width = 1.5 × 24.5 = 36.75 inches

The new width of the window should be 36.75 inches
