alexira [117]

Answer:

784 in²

Step-by-step explanation:

Let the original side is x.

1 foot = 12 inches

New sides of a rectangle are:

x + 12 and x - 4

The area of rectangle is:

(x + 12)(x - 4) = 960

Solve for x:

x² + 8x - 48 = 960
x² + 2*4*x + 16 - 64 = 960
(x + 4)² = 1024
x + 4 = 32
x = 28

Area of the original blanket:

A = 28² = 784 in²

Brent is designing a poster that has an area of 1 sq.ft. He is going to paste a photo collage on a section of the poster that is

ad-work [718]

Answer:54 th

Step-by-step explanation:

Given

Poster has an area of $A=1\ ft^2$

Size of photo is $\frac{1}{3}\ ft\times \frac{3}{5}\ ft$

and we know

$1\ ft\ \text{is equal to}\ 0.3048\ m$

so $\frac{1}{3}\ ft$ is $0.1016\ m$

$\frac{3}{5}\ ft$ is $0.1828\ m$

So area of photo is

$a=0.1016\times 0.1828$

$a=0.01858\ m^2$

ratio of area of photo and poster is

$\Rightarrow \frac{a}{A}=\frac{0.01858}{1}\approx \frac{1}{53.819}\approx \frac{1}{54}$

So photo will acquire $54^{th}$ Part of poster
