Mikaela placed a frame around a print that measures 10 inches by 10 inches. The area of just the frame itself is 69 square inche
olchik [2.2K]

Answer:

1.5 in

Step-by-step explanation:

Let x be the width of the frame.

Side of print=10 in

Area of frame=69 square in

We have to find the width of the frame.

Side of frame=10+x+x=10+2x

Area of square=(side)^2

By using the formula

Area of print=10\times 10=100in^2

Area of frame with print=(10+2x)^2

Area of frame=Area of frame with print-Area of print

69=(10+2x)^2-100

(10+2x)^2=69+100=169

(10+2x)=\sqrt{169}=\pm 13

10+2x=13

Because Side is always positive.

2x=13-10=3

x=\frac{3}{2}=1.5

Hence, width of frame=1.5 in
