MY NOTES ASK YOUR TEACHER EDUC 2010 In Suppose a company has to deal so frequently with the following kinds of shapes that they would find it handy to have formulas for their areas, Find formulas for the company using just the variable measurements indicated. (a) area = mj + -(m + n)(k -j) O area = my + - (m + n)(n -k) 160 area = mj + - (m + /)(k -n) O area = my + 5 (m + n) ( - k) cel O area = mj + = (m + n)(k -J) (b) Peri O area = = (pq + rs) area = (pq - rs) O area - - (pq + rs) Cares-(rs - pq) Cares = (rs - pq) 2 TT (c) the curves in this part are semicircles area = (# + 2) O area = (# - 2 12 O area = (* * 2 )+2 O area = (# + 212 O area = (# - 2) (d) the curve in this part is a semicircle area = VW - 8 area = vw + *V 8 area = vw + area = vw + my area = vw - *v 4 eBook
