Question

Find the area and perimeter

Answer 1

Area = 6a^4

Perimeter = 12a^2

Explanation:

from the measurements and from the figure it is a right triangle (triple of Pythagoras 3-4-5)

Area = 1/2 b × h

Area = 1/2 3a² × 4a²

Area = 1/2
`12a^(4)`

Area =
`6a^(4)`

----------------------------------

Perimeter

find the hypotenuse

by the rule of Pythagorean triples it is 5a²

so

3a² + 4a² + 5a² =

12a² (perimeter)
