To find the answer you simply find the square root of -169 which is 13 so x=13
30% = 30/100
= 0.3
Now if we say that x% of a number is y then it actually means that x% multiplied by that number would be equal to y, thus:
30%*56 = 0.3*56
= 16.8

Answer:
0.88m²
Step-by-step explanation:
Area of a trapezium = 1/2(a+b)h
a and b are the parallel sides
h is the height
Given
a = 1m
b = 1.2m
h = 0.8m
Substitute
Area of the trapezium = 1/2(1+1.2)(0.8)
Area of the trapezium = 1/2(2.2)(0.8)
Area of the trapezium = 1.1 * 0.8
Area of the trapezium = 0.88m²
