A rectangle has a perimeter of 18. The height of the rectangle is 4 cm. What is the area of the rectangle?
2 answers:
20 cm, I think
The perimeter is 18 and the height is 4 cm.
4 cm x 2 = 8
We are multiplying it by two because there are two side in a rectangle that are the same height
18 - 8 = 10
We are finding the length of the rectangle
10\2 = 5
The length of the rectangle is 5
5 x 4 = 20
That is the area
Answer:
20
Step-by-step explanation:
Perimeter of rectangle= 2l+2h so 2l+2(4)=18. SO 2l=10. l=5
Area=bh
(5)(4)=20cm

Answer:
Equate the divisor to 0
2x-1=0
2×=1
×=1/2
Putting onto the polynomial
f(1/2) = (1/2)³-1/2)²+3(1/2)-2
=-5/8
The correct answer is the last one
(0,-4)
Answer :- Just try area/2 or half the area of the triangle
