What is the altitude of a rhombus if its area is 50 square meters and the length on one side is 12.5 meters

SVETLANKA909090 [29]

<u>Answer:</u>

8 meters or 4 meters

<u>Step-by-step explanation:</u>

We know that for finding the area of a rhombus, there are two diagonal sides: one of which is 12.5 meters in length and the other one we'll assume to be y.

Then, we can write:

Area of rhombus = $\frac{1}{2} *12.5*y$

$50=\frac{1}{2} *12.5*y$

$y=\frac{100}{12.5}$

$y=8$ meters

If the sides of the rhombus are not internally diagonal, then we can simply use the following formula:

Area of rhombus = altitude * side

$50=a*12.5$

$a=4$ meters
