The area of rectangle ABCD is 72 square inches. A diagonal of rectangle ABCD is 12 inches and the diagonal of rectangle EFGH is
luda_lava [24]

Answer:

The area of rectangle EFGH is 242\ in^{2}

Step-by-step explanation:

For this problem I assume that rectangle ABCD and rectangle EFGH are similar

step 1

Find the scale factor

we know that

If two figures are similar, then the ratio of its corresponding sides is proportional, and this ratio is called the scale factor

Let

z ------> the scale factor

The scale factor is the ratio between the diagonals of rectangles

so

z=\frac{22}{12}=\frac{11}{6}

step 2

Find the area of rectangle EFGH

we know that

If two figures are similar, then the ratio of its areas is the scale factor squared

Let

z------> the scale factor

x -----> area of rectangle EFGH

y ----> area of rectangle ABCD

so

z^{2}=\frac{x}{y}

we have

z=\frac{11}{6}

y=72\ in^{2}

substitute and solve for x

(\frac{11}{6})^{2}=\frac{x}{72}

\frac{121}{36}=\frac{x}{72}

x=\frac{121}{36}(72)

x=242\ in^{2}
