7 0

Answer:

Step-by-step explanation:

area of top=7×6=42 yd²

area of bottom=3×6=18 yd²

area of two rectangles=2[4×6]=48 yd²

area of two trapezoids=2[1/2(7+3)×3.5]=35 yd²

total surface area=42+18+48+35=143 yd²

28/21 = 42/x solve for x

Scilla [17]

28/21=42/x multiply both sides by x

28/21x=42 divide by 28/21 on both sides ( or multiply both sides by 21/28)

X= 63/2
X= 31 1/2

Find the area of a trapezoid with a base of 21.6 m, a height of 4.5 m, and top of 11.9 m. Round your answer to the nearest hundr

Serga [27]

Answer:

$A=75.37\ m^2$

Step-by-step explanation:

Given that,

The base of a trapezoid, b = 21.6 m

Height of the trapezoid, h = 4.5 m

The tope of the trapezoid, a = 11.9 m

We need to find the area of a trapezoid. The formula for the area of a trapezoid can be given by :

$A=\dfrac{1}{2}\times (sum\ of\ parallel\ sides)\times height$

Put all the values,

$A=\dfrac{1}{2}\times (21.6+11.9)\times 4.5\\\\=75.37\ m^2$

Hence, the area of a trapezoid is equal to $75.37\ m^2$ .
