Step-by-step explanation:
length = 5×width + 1
perimeter = 2×length + 2×width =
= 2×(5×width + 1) + 2×width =
= 10×width + 2 + 2×width = 12×width + 2
Answer:
a=4 B i think is =20 c im not sure
Step-by-step explanation:
We would first change 102% into a decimal which would be 1.02 in which we would multiply that by 2000 in which we would get 2040 which is your answer ^^
___
/ ___ \ Let's imagine a trapezoid looks like this. The two parallel lines would be the top and the bottom lines.
The 10 in. side would be either the top or bottom line. The other parallel line is twice as long, meaning it's 2 times longer. So you multiply 10 in x 2 = 20 in.
The given side length = 10 inches.
Height = half as long, meaning it's half of 10 in. = 5 in.
Formula of a trapezoid =
x height
Where a and b are bases. The top and bottom of the trapezoid are bases.
Area trapezoid =
x 5 =
x 5 = 15 x 5 = 75 in² <-- area means the unit is squared
Answer:
area of rectangle =length ×width
area of rectangle=12yd×15yd
area of rectangle=180yd²
