Answer:
Area = 8 square ft
Step-by-step explanation:
Area of a rectangle = Length × width
suppose length = x
width = y
Here it is given that x = 3 y - 2
width is given as y = 2 ft
∴ x = 3 × 2 -2
x = 6 -2
x = 4
Area of rectangle = length × width
A = 4 × 2
= 8 square ft

Step-by-step explanation:
Answer:
145 yd²
Step-by-step explanation:
There will be dour triangular faces. For a triangle, area is given as
A=½bh where b is base and h is height. The base will be 5 yards and h is 12 yards hence for one triangular face, area will be ½*5*12=30 yd²
Since they are four similar triangles, area of triangular faces will be 30*4=120 yd²
The surface area of a square base is given by
A=a*a=a² where a is the dimension of one side. Given that the meaurement is 5 yards then A=5²=25 yd²
Total area will be the sum of triangular and square faces hence 120+25=145 yd²
