Answer 1

Answer:

a)E has greater area

b)56cm

c) square B,and ,D

Step-by-step explanation:

(a) area of square B = (a)2

a= 6

area = 36cm2

area of rectangle E = L × B

L = 12

B= 4

Area = 12×4=48cm2

: area of rectangle E has greater area

(b) if square A is removed then perimeter =

6+6+6+6+6+6+4+4+6+6 = 56cm

(c) area of square A and square D = (a)2 + (a)2

a = 6

(6)2+(6)2

36+36= 72cm2

area of square B + area of rectangle E

area of square B = 36cm2 ( solve above )

area of rectangle E = 48cm2 ( solve above )

area = 36 + 48 = 84cm2

area of square A , C and D

area of square = (a)2

a = 6

(6)2+(6)2+(6)2

area = 36+36+36 = 108cm2

area of square A , C and D = 108 has greater area
