Question

Which one of the following is an equable shape ? Choose the correct option a ) Figure A b ) Figure B c ) Both Figure A and B d ) Neither Figure A and B

Answer 1

ANSWER

option 1 is correct

EXPLANATION

FIGURE 1

area of rectangle = 16.2 square unit

perimeter of rectangle = 16.2 unit

area = perimeter

so it is equable shape

FIGURE 2

here perpendicular divide triangles into two equal triangle

so by using Pythagoras theorem in one triangle

hypotenuse = 5

now

area = 1/2 × 4 × 3 = 6 square unit

perimeter = 5+5+3+3 = 16 unit

area not = perimeter

so it is not equable

Answer 2

Answer:

FIGURE 1

PERIMETER

2(l+b)= 2(3.6+4.5)= 2(7.9)= 15.8

AREA

l×b = 3.6 × 4.5 = 16.2

SO FIGURE IS NOT EQUABLE

FIGURE 2

AREA

1/2 b×h

1/2×6×4=12

Perimeter by Pythagoras Theoram

5+5+6=16

so option d is correct
