A quick eye-balling of a T-72 with ERA and doing some maths suggest to me no more than ~160 square feet of ERA, for 160 x 90 = 14,400 pounds, or 7.2 tons.

From a PDF I fond on msm.sk

The total weight of all blocks of ERA is 2700 kg per one tank whilst the weight of blocks there on
turret is 1 170 kg. Increased weight effects have been tested in the course of qualification and user tests.
