Answer:
A = 105 cm²
Step-by-step explanation:
The area (A) of the trapezoid is calculated as
A = [ (b₁ + b₂)h ]
where h is the height and b₁, b₂ the parallel bases
Here h = 5 , b₁ = 24 and b₂ = 18 , then
A = [ (24 + 18)5 ]
= (42 × 5)
= × 210
= 105 cm²
The value of given expression when x=-4 and y=4 is 1250.
The expression is missing in the question which is .
We have to solve it for x= -4 and y = 4.
Now putting the value of x and y we get,
Hence the value of given expression when x=-4 and y=4 is 1250.
