Answer:
21 and 10 :) hope it helps
Step-by-step explanation:
A^2 + b^2 = c^2
3^2 + 4^2 = c^2
9 + 16 = c^2
25 = c^2
5 = c
Answer:
A = 27 cm²
Step-by-step explanation:

Putting in the above formula
A = (10.8)(2.5)
A = 27 cm²
Step-by-step explanation:
Area for a right angle triangle = 1/2 bh
b = Base
h = Height
A = 1/2×bh
= 1/2 × 2c^3d^2 × 4c
= (2c^3d^2 × 4c) / 2
= c^3d^2 × 2c
= 2c^4 × d^2
