The area of a triangle is BH/2 (base x height / 2).
Base = 9
Height = 5
9*5 = 45;
45 / 2 = 22.5
Your area is 22.5 ft
I hope this helps!
Answer:
6) a) 15 inches
7) b) 4 cm
The side of the square 4 cm
8) C)
Area of the square = side ×side
Step-by-step explanation:
<u><em> Step(i):-</em></u>
Given that the perimeter of the square is twice the perimeter of the triangle
we know that the perimeter of the square = 4a and
The perimeter of the triangle = a+b+c
Given that the perimeter of the square is twice the perimeter of the triangle
4a = 2( a+b+c)
2a = 11 +9+10
2a = 30
a =15
The side of the square = 15 inches
<u><em>Step(ii):-</em></u>
<em>7) </em>
Given that the area of the square is equal to the area of the rectangle
a² = length × breadth
a² = 8×2 =16
a= √16
a = 4cm
8)
Area of the square = side ×side
To find the biggest fraction you need to convert them to decimals.
a) 5/6
b) 5/12
c) 19/45
d) 13/14
e) 7/11
f) 1/2

First off, you can multiply a 2-digit number by 2 and just add 0 to the product. For instance: 12 x 20
Number line: two jumps of number 12.
So : 12 x 2 = 24
Finally, 12 x 20 = 240
Hope this helped.
