The triangular prism given here is consisting of two triangles and three rectangles

So the area of the triangular prism = area of the two triangles and the area of the three rectangles

= Surface Area ₚᵣᵢₛₘ =[2 ×1/2×8×6] m²+[3×7×10]m²

= (48+210)m²

= 258m² (ans)

A flower bed is in the shape of a triangle with one side twice the length of the shortest side, and the third side is 14 feet mo
umka21 [38]

Answer:

The dimensions of triangle are 66 ft, 33 ft and 47 ft

Step-by-step explanation:

Let

x -----> the length of one side

y -----> the length of the shortest side

z -----> the length of the third side

we know that

The perimeter of triangle is

P=x+y+z

P=146\ ft

so

146=x+y+z -----> equation A

x=2y -----> equation B

z=y+14 ----> equation C

Substitute equation B and C in equation A and solve for y

146=2y+y+y+14

146=4y+14

4y=146-14

4y=132

y=33\ ft

<em>Find the value of x</em>

x=2(33)=66\ ft

<em>Find the value of z</em>

z=33+14=47\ ft

therefore

The dimensions of triangle are 66 ft, 33 ft and 47 ft

Multiplying two number with the same base has as result a number with the same base and the sum of the exponents so:

1/2 + 3 = 7/2
which means
5^3 x 5^(1/2) = 5^(7/2)
