Question

In the figure, BM and DL are heights of ||gm ABCD. If height BM = 15 cm, AD= 12 cm and DL = 10 cm. Find the length of AB

Answer 1

Answer:

28 cm

Step-by-step explanation:

in triangle DLA and triangle BMA

(a) angle DLA= angle BMA

(b) angle A is common angle

therefore; DLA,BMA are similar

then; AB/AD=BM/DL

now;

AB/AD=15/10 [putting the values of BM,DL]

or, AB/12=15/10 [putting the value of AD]

or, AB=280/10

or, AB=28

therefore; length ofAB is 28 cm ANSWER
