Answer:
B= 15 cm²
Step-by-step explanation:
The base of the triangular shaped wedge of cheese is a right-triangle.To find the area of a right-triangle you apply the formula for half base by height.
A=1/2*b*h = base area = B
In this case, assume the sides of the triangle given are; a=5 cm and b=6 cm, thus area will be 1/2*6*5 =15 cm²
B= 15 cm²
b = i+12
b-3 = 4( i-3) ------> b-3=4i-12 ----->b=4i-9
b = i+12
b=4i-9
i+12=4i-9
21=3i
i=7
b= i+12
b=7+12=19 Ben is 19 years old now
