The expression is equal to 2a(2a_8) a2,_10
To find the area you just find the area of each triangle.
To do this use the formula b×h×.5=A
6×4×.5=A
A=12
Now you just multiply 12 by 4. The reason you multiply by 4 is because you have 4 triangles that make up the rhombus. The area of the rhombus is 48cm²
11
(9, 18, 27, 36, 45, 54, 63, 72, 81, 90 and 99)
Those numbers divisible by 9 are the multiple of 9; thus need to know how many multiples of 9 there are between 1 and 100:
100 ÷ 9 = 11 r 1 ÷ last multiple of 9 is 11 × 9 (= 99)
→ There are 11 - 1 + 1 = 11 numbers between 1 and 100 which are divisible by 9.
(They are 9, 18, 27, 36, 45, 54, 63, 72, 81, 90, 99.)
