What is the surface area of a rectangle 3 m long 1 m wide and 2 m at the bottom

4.18 meters^2 or 41800 centimeters^2

Step-by-step explanation:

Surface Area = 2×(2×1 + 2×0.03 + 1×0.03) = 4.18 meters2

Surface Area = 2×(200×100 + 200×3 + 100×3) = 41800 centimeters2

step-by-step explanation: given equation a = h(b 1+b 2)

also we are given values of a, h and b 1 as :

a = 16, h = 4, and b 1 = 3.

in order to solve it for b 2, we need to plug the given values of   a, h and b 1 .

therefore, plugging values of   a, h and b 1   in given equation, we get

16 = 4( 3 + b 2)

first dividing both sides by 4, we get

4 = 3 + b 2

subtracting 3 from both sides, we get

4 -3 = 3 -3 + b 2

1 = b 2.
