Answer:
234
Step-by-step explanation:
The consecutive terms of the sequence have a common difference d
d = 17 - 10 = 24 - 17 = 7
This indicates the sequence is arithmetic with n th term
= a₁ + (n - 1)d
where a₁ is the first term and d the common difference
Here a₁ = 10 and d = 7 , thus
= 10 + (32 × 7) = 10 + 224 = 234
There are 8 girls in the whole class.
32÷4= 8
1/4 = 8/32
Divide the figure into two parts, a triangle and a square
TRIANGLE
the base (b) = 5 cm
the height (h) = 4 cm
Calculate the area of the triangle
a = 1/2 × b × h
a = 1/2 × 5 × 4
a = 20/2
a = 10
The area of the triangle is 10 cm²
SQUARE
the side (s) = 5 cm
Calculate the area of the square
a = s²
a = 5²
a = 25
The area of the square is 25 cm²
THE AREA OF THE FIGURE
a figure = a of triangle + a of square
a figure = 10 + 25
a figure = 35
The area of the figure is 35 cm²
