Answer:
100mm²
Explanation:
the other side: (50 - 20 × 2) ÷ 2 = 5
5 × 20 = 100
Answer:
Subtract given lengths: 50 - 20 = 30
Divide by 2 since there are 2 missing sides that need a length: 30 divided by 2 = 15
With the given side lengths multiply all of them to get your area.
15 x 20 = 300 is your area I am pretty sure.
