Question

What is the surface area of the solid that this net can form? A net has 2 rectangles. One rectangle has a base of 25 millimeters and a height of 21 millimeters. The other rectangle has a base of 41 millimeters and height of 5 millimeters.

Answer 1

Answer:

730mm²

Step-by-step explanation:

Answer 2

Answer:

S.A = 730mm²

Step-by-step explanation:

Since the solid is made up of two rectangles. Then the surface area (S.A) would be

S.A = area of first rectangle + area of second rectangle

Since the first rectangle has it's base to be 25mm and height to be 21mm, then it's area is

25mm x 21mm = 525mm²

Since the second rectangle has it's base to be 41mm and height to be 5mm, then it's area is

41mm x 5mm = 205mm²

Therefore

S.A = 525mm² + 205mm² = 730mm²
