the other parallel side is 30 cm
Step-by-step explanation:
here's the solution :-
let the other parallel side be x
now,
=》Area of trapezium =
![\frac{1}{2} \times sum \: of \: parallel \: sides \times height =》[tex] \frac{1}{2} \times (x + 20) \times 16 = 400](https://tex.z-dn.net/?f=%20%5Cfrac%7B1%7D%7B2%7D%20%20%5Ctimes%20sum%20%5C%3A%20of%20%5C%3A%20parallel%20%5C%3A%20sides%20%5Ctimes%20height%20%3C%2Fp%3E%3Cp%3E%3C%2Fp%3E%3Cp%3E%3C%2Fp%3E%3Cp%3E%3D%E3%80%8B%3C%2Fp%3E%3Cp%3E%5Btex%5D%20%5Cfrac%7B1%7D%7B2%7D%20%20%5Ctimes%20%28x%20%2B%2020%29%20%5Ctimes%2016%20%3D%20400)
=》( x + 20 ) × 8 = 400
=》x + 20 = 400 ÷ 8
=》x = 50 - 20
=》x = 30
so length of other parallel side = x = 30 cm
Answer:
The table that has a consistent proportionality between Y and X of 2 is choice 2.
Step-by-step explanation:
Because the proportionality between X and Y is 2, that means for each x value, the corresponding y value will be twice as big. The only option that meets this requirement is choice 2, so that is the correct answer.
Answer:
Area of the rectangular doormat = 2/5 m²
Step-by-step explanation:
Length of the rectangular doormat = 4/5m
Width of the rectangular doormat = 1/2m
What is the area of the doormat?
Area of a rectangle = length × width
= 4/5m × 1/2m
= (4×1) / (5×2)
= 4 / 10
= 2/5 m²
Area of the rectangular doormat = 2/5 m²
