40/100 simplify that and you will get .4.
Dc=ac
Step-by-step explanation:
Factor the numerator and denominator and cancel the common factors.
4x^4 - 2
I think the answer would be 38in^2
Because the equation is : (a+b) *h / 2
A and b are both the bases of the trapezium
So (11 + 8) these are the bases and the height is 4 so you would do
(11+8)*4 / 2
(19)*4 / 2
76 / 2
= 38
