Question

A rhombus has diagonals 500 yd and 800 yd in length. Find the area in square miles.

Answer 1

We know that
A simple formula for the area of a rhombus when you know the lengths of the diagonals is half the product of the diagonals

Area=d1*d2/2
d1=500 yd
d2=800 yd

1 mile is equal to -----> 1760 yd
x mile---------------> 500 yd
x=500/1760----> x=0.2841 mi

1 mile is equal to -----> 1760 yd
x mile---------------> 800 yd
x=800/1760----> x=0.4545 mi

Area=(0.2641*0.4545)/2-----> 0.06 miles²

the answer is
0.06 miles²
