adell [148]

Answer:

The playground covers $\frac{1}{5}$ of a square mile

Step-by-step explanation:

The playground is a rectangular ground. The area of a rectangle is given by legth * width, hence,

The area of the playground is length * width

Area = $\frac{3}{5}*\frac{1}{3}=\frac{3}{15}=\frac{1}{5}$ sq. mi

Hence the playground cover $\frac{1}{5}$ of a square mile

Can someone help please :)

andrew-mc [135]

Answer:

x = 5

Step-by-step explanation:

These triangles are similar, so they are in proportion to each other. Because of this we can say $\frac{2.5}{3.5}$ (the lengths of the vertical sides) = $\frac{x}{7}$ (the lengths of the hypotenuses). If we solve by cross-multiplying the numbers and then dividing we get x = 5.
