Answer:
360cm
Step-by-step explanation:
The top square is 10 x 13 = 130
The middle square is 10 x 12 = 120
Both side triangles are 5 x 12 = 60. You would halve it but there are two triangles.
5 x 10 = 50
50 + 120 = 170
170 + 130 = 300
300 + 60 = 360
Equation would be (10 x 13) + (10 x 12) + (5 x 12/2) + (5 x 12/2) + (10 x 5)
The equation options seem like they are missing some numbers or something
£10
Step-by-step explanation:
firstly what you have to do is
since the percentage is decreased
we will say 100 - 25% = 75%
then we say 7.50/75% = 10
So we know that the original price was
£10 pounds
As 10- 25%= 7.5
I'm not totally positive but I got 2131.2
