Answer 1

Answer:

• 30cm +27cm =57cm
• 10cm +6cm=16cm
• 17cm +8cm =25cm
• 57cm+16cm+25cm =
• 50cm+10cm+20cm=80cm
• 7cm+6cm+5cm=18cm
• 80cm+18cm=98cm

Answer 2

Answer:

2064cm²

Step-by-step explanation:

The total surface area of a shape is given by the area of each side. In this case 2 × the trapezium/trapezoid, 1 × the top side, 1 × the bottom side, 1 × the left slanted side and 1 × the right slanted side.

Let's start with the trapeziums/trapezoids. The formula for their area is $\frac{1}{2}$h(a+b). In this case, because there are 2, we can work them out at once without the $\frac{1}{2}$.

By substituting a with 6cm (the top length), b with 27cm (the bottom length), and h with 8cm (the height), the equation becomes 8(27+6) or 8×33, which can be solved to 264cm².

The rest of the sides are rectangles, which use the formula lw for area. For the top side, this is 6×30, or 180cm².

For the bottom side, this is 27×30, or 810cm².

For the left slanted side, this 10×30, or 300cm².

For the right slanted side, this is 17×30, or 510cm².

We should add these all together to get the final result. This equation is 264+180+810+300+510. This adds up to 2064cm².
