Answer:
The length of the longer base he 35 units
Step-by-step explanation:
Here, we want to find the length of the longer base of the trapezoid
Mathematically, we can find the area using the formula;
1/2( a + b) h
where a is the shorter base
b is the longer base
h is the height
Let the shorter base be x
The other base is 5 times this length and that makes 5 * x = 5x
Height is the average of both bases;
(x + 5x)/2 = 6x/2 = 3x
Substituting these in the formula, we have ;
1/2(x + 5x)3x = 441
3x(6x) = 882
18x^2 = 882
x^2 = 882/18
x^2 = 49
x^2 = 7^2
x = 7
But the longer base is 5x and that will be 5 * 7 = 35 units
Answer:
The first one is 648 and the second one is 11,600
Step-by-step explanation:
The answer is D. The answer is D because you just keep multiplying each number by the same number.
6 • 8 = 48
7 • 8 = 56
Hello :
by the pytagore rule :
the length of the hypotenuse is x : x²= (5√6)² +(5√6)²
x² = 300
x =√300
