Answer:
54m2
Step-by-step explanation:
Cut the shape into two - from the 9m length. One has 3m by 8m(ie 5m + 3m) dimensions, and the other 6m(ie 9m - 3m) by 5m dimensions.
Taking area of first one=24m2,then area of the second =30m2.
To get area of whole shape, we add both areas=54m2
NB:Area=l×b
Answer:
Jenny gets €18.
Step-by-step explanation:
Jenny gets 3 of every Laura's 2. First you add together both numbers in the ratio. 3+2=5. Then you divide the constant, 30, by the sum, 5. 30/5=6. Then you multiply each number of the ratio by the quotient. 3 x 6=18.

Answer:
96feet
Step-by-step explanation:
Given the height, in inches, of a spray of water is given by the equation ℎ(x)=160−16x^2
x is the number of feet away from the sprinkler head the spray
To get the height of the spray 2 feet away from the sprinkler head, we will simply substitute x =2 into the function and et the height h as shown;
From the equation
ℎ(x)=160−16x^2
h(2) = 160-16(2)²
h(2) = 160-16(4)
h(2) = 160-64
h(2) = 96feet
Hence the height will be 96feet if the spray is 2feet away from the sprinklers head
