An Equilateral triangle is divided into 4 congruent equilateral triangles. What method can be used to find the area if the larger triangle, given the area of one of the smaller triangle? A. Multiply the area of the area of the larger equilateral triangle by 4 B. Multiply the area of one of the congruent equilateral triangles by 4 C. Subtract the area of one congruent triangle from the area of the larger equilateral triangle D.Add the area of the larger equilateral triangle to the areas of the 4 congruent equilateral triangles Please explain
Wow, you are fast! Thanks! Please explain?
Well if you divide a triangle into 4 triangle you simply multiply the area of that little triangle by 4 to get the area of the larger one LIKE THIS |dw:1334968297347:dw|
@angeldreamgurl it has to be congruent so it looks like this...but just same formula lol |dw:1334968350711:dw|
