Area of triangle = base x height x 1/2
Area of the triangle:
= 12 x 15 x 1/2
= 180 x 1/2
= 90 units^2
Answer:
I think it is 1
Step-by-step explanation:
I am sorry if it is not correct
Answer:
Step-by-step explanation:
1. Value of x
The diagonals of a rectangle are equal, so
PR = QS
2. Length of each diagonal
PR = 11x - 20 = 11×18 - 20 = 198 - 20 = 178
QS = x + 160 = 18 + 160 = 178
The length of each diagonal is 178.
