An equilateral triangle with the lengths of its sides given in terms of a and b.
(4a)cm
(3b)cm
(a + b + c)cm
Find a and b and hence find the length of the
sides of the triangle.

Step-by-step explanation:

4a = 3b

4a = a+b+c

c = 3a-b, so

4(3a-b) = 3b

12a-4b = 3b

12a = 7b

subtracting,

8a = 4b

or

4a = 2b

But, 4a = 3b, so

2b = 3b

b=0

46.2+112.3

the figures below are made out of circles, semicircles, quarter … find the area and the perimeter of each figure and give your answers as a completely simplified exact value in terms of π (no approximations). remember that we'll also have to cut whatever areas we get in half, since we're only dealing
