Hey!
------------------------------------------------
Surface Area Formula: 2LW * 2LH * 2WH
------------------------------------------------
2LW:
5 x 1 = 5
5 x 2 = 10
------------------------------------------------
2LH:
4 x 1 = 4
4 x 2 = 8
------------------------------------------------
2WH:
5 x 4 = 20
20 x 2 = 40
------------------------------------------------
Surface Area:
40 + 8 + 10= 58
------------------------------------------------
Answer:
D) 58 cm2

Answer:
The daughter is 36 years old and the son is 12 years old.
Answer:
1. 70.
2. 29.
3. 442.5
4. 289.
5. 632.
Step-by-step explanation:
The key to doing these is to split the polygons into rectangles, triangles or trapezoids as appropriate.
For example, number 1 consists of a rectangle area 8 * 8 and another of 3* 2.
So the area = 64 + 6 = 70 unit^2.
2. The area = sum of 3 rectangles 1*1 + 4*6 + 2*2.
3. Area = 11*15 + 11*15 + 1/2*15*15
4. Area = 18*12 + 1/2 * 6 * 15 + 1/2 * 7 * 8.
5. Area = area of 2 rectangles + area of a trapezoid.
= 18 * 24 + 4*10 + 1/2(12 + 20) * 10.
