Hope this helpsss
Answer:
25 = 1/2(3 + 7)h
5 feets
Step-by-step explanation:
Given that:
Window shaped in the form of a trapezium :
The length of its bases :
Top of window base = 3 feets
Bottom of window base = 7 feets long
Area of Windom = 25 feets²
Recall :
Area of a trapezium is given by :
Area, A = 1/2(a + b)h
a and b are the bases
h = height
Inputting the Given values into the equation :
25 = 1/2(3 + 7)h
Hence, the height of the window can be Obtian using the expression
25 = 1/2(3 + 7)h
25 = 1/2(10)h
25 = 5h
h = 25 /5
h = 5 feets
