Question

PLEASE HELP AND SHOW STEPS

Answer 1

the answer is 12 units for sure

do u need explanation?

if B -4,0

and a -7,0

so the distance between them is 3

and c -7,4 so the distance between CA is 4

by Pythagoras Theorem to get CB

(4×4) + (3×3) = 16+9=25

SO WE MAKE A SQUARE ROOT ON 25

it will be 5 so the perimeter equal 4+5+3=12
