Question

State true or false:

The area of $△XYZ$ in which $XY=YZ=ZX=4.5$ cm is $8.77$ $c{m}^2$, approximately.

• A. True
• B. False

Answer 1

The correct option is A True

Since, all the sides of $△XYZ$ are equal, therefore it is equilateral.

Area $\left(△XYZ\right)=\frac{\sqrt{3}}{4}{a}^2=\frac{\sqrt{3}}{4}(4.5{)}^2=8.77c{m}^2$
