Area of a triangle = 1/2 b h. Using this formula, we can find the one we need. Plug the numbers we have into the formula, and we get: 24 = 1/2 b 4 6 = 1/2 b 12 = b The base is 12 meters. c) 12 m
Area of a triangle is A=1/2×base×height Now you can do this in two ways: 1) A=1/2×base×height 24=1/2×b×4 24= 2×b ( take half of 4) 24/2=2/2×b 12=b Therefore the base of the triangle is is 12 metres Isolate b ( base) 2) A=1/2×b×h A(2)=1/2(2)×b×h 2A=2/2×b×h 2A=1×b×h 2A/h= b×h/h 2A/h=b So substitute the numbers in and solve: 2A/h=b 2(24)/4=b 48/4=b 12=b Thus the base of the triangle is 12m
