Question

The corresponding sides of ΔABC and ΔDEF have equal lengths. The area of ΔABC is 4 square units, and the longest side of ΔDEF is 5 units long. What is the area of ΔDEF? PLEASE HELP!!

Answer 1

The area of ΔDEF will be
`4` square units.

Explanation:

The area of
`\triangle ABC` is
`4` square units.

The corresponding side lengths of
`\triangle ABC` and
`\triangle`DEF are equal.

That means, two triangles are congruent according to
`SSS` postulate.

So, their area will be also equal.

Thus, the area of ΔDEF will be
`4` square units.
