The length is 4.5ft. Explanation... Perimeter= ( L2 + W2 ) we know that the perimeter is 19ft and the width is 5ft. 19= L2 + 5•2 19= L2 + 10 19-10= 9 (L2) So divide 9 by 2. 4.5 perimeter is 19, length is 4.5 and the width is five.
Ratio = 2:3 Let smaller angle be 2x Let bigger angle be 3x Sum of two complementary angles = 90 2x + 3x = 90 5x = 90 x = 90/5 = 18 Smaller angle = 2x= 2*18 = 36 I hope it is helpful :D
